after the water is wrung, the wringing part 6 is pushed downwards, when the rack 8 moves to the position of the second step 26 and the inclined plane/cambered surface, a larger pushing force is applied or the locking of the limiting mechanism is released, so that the first step 25 and the second step 26 are abutted, the first ratchet 16 and the second ratchet 17 are separated, under the action of the torsion spring, the side plate 4 is turned upwards to reset, the wiping object is unfolded along with the side plate 4 and drives the rotating part 5, the wringing gear 10 and the one-way gear to rotate and reset, the mop is rotated, the wringing part 6 is automatically separated from the rack 8, the mop can be switched to a mopping state, and the wringing is completed.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
